$nglow = '#FFFFFF';
if( ereg("^|#([A-Za-z0-9]{4})",$nglow,$testvar) )
{
echo "Invalid hex code";
}


That will work right to match a hex. Even when typed like so: #fFfFfF ?

$nglow = '#0f2452';
if (!preg_match('#\#(?:[A-F]|[0-9]){6}#i', $nglow))
{
echo 'invalid hex code';
}

what you have would only accept A-Z where hex is only A-F | 0-9

Ok i need one more. It needs to make sure that the variable $theurl starts with http:// and ends in .mid :)?

if(preg_match('#^http://(.*)\.mid$#', $theurl)) {
// it matches
}

[Scott MacVicar]

evil code syntax ;)
and its case sensitive.
he really means

if (preg_match('#^http://(.*)\.mid$#s', $theurl))
{ // it matches

}

How about if you want to make .mid be able to be .html, .php, or .shtml. (a.k.a multiple string check at the end)
